To have a general view, a trip with the touristbus is fine, after that I would prefer to walk around and sense the atmosphere and look at details. In Barcelona they have a very good system. Every ten minutes, a new bus arrive. You can get out to see any place you like, and then continue with the next bus,- all day at the same ticket. When you buy the ticket, you get a guide book, with explanations about the sights at every stop.

Visiting ´DK is a good idea, Ginger, remember to tell me if you start planning.

A tour bus would be good to get a general overview of a new place like Copenhagen. I’ve seen such buses in London, Bath (UK), New York City (USA) and Washington, DC (USA). Also, use the Internet. Researching travel destinations is so much easier then 20 years ago.
